Mon, 23 Jun 2014 13:12:04 -0400 Mike Pavone Ensure proper stack alignment when the Z80 calls into C code. This fixes a crash in optimized builds on OSXdefault tip
Mon, 23 Jun 2014 11:46:56 -0400 Mike Pavone Save and restore guest address in the write function for a code memory chunk in the "slow" path for inconvenient host addresses. This fixes an intermittent crash on OSX in the code that checks whether the memory written may contain code
Mon, 23 Jun 2014 11:05:55 -0400 Mike Pavone Fix x86_rrindex_sizedir. Pass the correct scale to mov_rindexr in gen_mem_fun. BlastEm now sort of works on OS X. Runs reliably from lldb, but only intermittently from the shell
Tue, 17 Jun 2014 01:50:29 -0400 Mike Pavone blastem builds and almost works on OS X now
Mon, 24 Feb 2014 01:30:16 -0800 Mike Pavone Use a typedef code_ptr in place of uint8_t * in 68K core to better support host instruction sets with different instruction word sizes. Make x86_68k_options contain a cpu_options so that gen_mem_fun can eventually be shared with the Z80 core.
Mon, 24 Feb 2014 00:50:15 -0800 Mike Pavone Rename x86_backend.h and x86_backend.c to backend.h and backend.c respectively
Mon, 24 Feb 2014 00:40:32 -0800 Michael Pavone Fix build breakage
Mon, 24 Feb 2014 00:39:02 -0800 Michael Pavone Start work on refactoring some of the backend code to allow more sharing between M68K and Z80 cores and possibly also between x86 and the ARM backend when it exists
Sun, 23 Feb 2014 22:17:43 -0800 Michael Pavone Fix ARM code generation and test program
Sun, 23 Feb 2014 21:37:19 -0800 Mike Pavone Added untested code for generating ARM machine code

Tue, 18 Feb 2014 20:32:10 -0800 Michael Pavone Generate get_sr, set_sr and set_ccr at runtime so they can respect the flag_regs setting
Mon, 17 Feb 2014 19:58:37 -0800 Michael Pavone Make references to flags in the M68K core respect the flag_regs options array so that flags can be moved out of registers for the 32-bit port. set/get ccr/sr still need to be updated to support this, but everything else should be done.
Sun, 16 Feb 2014 19:54:27 -0800 Michael Pavone Generate handle_cycle_limit at runtime so it can use the generated save/load_context functions. Since the hand written versions of save/load are no longer used they have been removed.
Sun, 16 Feb 2014 19:21:39 -0800 Michael Pavone Generate native_addr and native_addr_and_sync at runtime so they can use the generated save/load_context functions
Sun, 16 Feb 2014 18:17:59 -0800 Michael Pavone Generate retrans_stub at runtime so it can use the generated save/load_context functions
Sun, 16 Feb 2014 16:50:10 -0800 Michael Pavone Removed old debug print function that is no longer needed
Sat, 15 Feb 2014 22:35:18 -0800 Michael Pavone Get rid of the native stack option the 68K core. Trying to make it work with code that messes with the stack is not worth the trouble.
Sat, 15 Feb 2014 21:25:36 -0800 Michael Pavone Generate m68k_start_context at runtime so it can use the generated load_context and save_context
Fri, 14 Feb 2014 19:56:18 -0800 Michael Pavone Generate save_context and load_context functions at runtime

Sun, 09 Feb 2014 17:16:55 -0800 Mike Pavone Added step and step-over debugger commands. step-over is like next except it doesn't follow conditional branches to lower addresses. This makes it useful for advancing to the end of a loop. Also fixed a bug in next introduced by the refactor.
Sun, 09 Feb 2014 12:35:27 -0800 Mike Pavone Refactor debugger next command
Sun, 09 Feb 2014 10:29:29 -0800 Mike Pavone Properly handle dbcc, rtr and rte in the debugger next command

Sat, 08 Feb 2014 23:37:09 -0800 Mike Pavone Initial GDB remote debugging support. Lacks some features, but breakpoints and basic inspection of registers and memory work.
Fri, 07 Feb 2014 21:18:05 -0800 Michael Pavone Implement per-channel wave logging and primitive looping support in vgm player.
Fri, 07 Feb 2014 00:41:51 -0800 Michael Pavone Properly clamp envelope value to zero when it overflows during the attack phase. This fixes a number of instruments that sounded rather wrong as well as the missing melody line from Mushroom Hill Zone in Sonic and Knuckles

Mon, 03 Feb 2014 09:18:10 -0800 Michael Pavone Initial attempt at emulating extended bank area access delays when 68K bus is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.
Tue, 28 Jan 2014 08:36:06 -0800 Michael Pavone Add 3 wait states to Z80 access to bank area since that seems to be roughly the average in normal usage
Mon, 27 Jan 2014 22:12:22 -0800 Michael Pavone Fix timing of certain ld and jp instructions in the Z80 core
Mon, 06 Jan 2014 22:54:05 -0800 Michael Pavone The local clone on my laptop got messed up and some changes had not been pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.
Thu, 31 Oct 2013 01:00:32 -0700 Mike Pavone Add support for left and right shift keys
Thu, 31 Oct 2013 00:28:27 -0700 Mike Pavone Small optimization for H40 mode
